SPECIFICATION forming part of Letters Patent No. 634,967, dated October17, 1899.

Applicatien filed OctoberZO, 1898- gel'ial NO- (N0 modem To a l! Ir/tom,it may concern:

Be it known that I, WILLIAM NV. TYLER, a citizen of the UnitedStates,residing at Dayton, in the county of Montgomery and State of Ohio, haveinventedcertain new and useful Improvements in Turbine'lVater-Wheels, ofwhich the following is a specification.

Myinvention relates to improvements in turbine water-Wheels; and itespecially relates to that class of wheels which are arranged in pairs,two wheels on the same horizontal shaft, within an outer cylinder orpenstock.

The object of my invention is to provide an arrangement for wheels ofthis character which shall be simple, strong, and compact inconstruction and one in which the water is conveyed to the wheelsin'such a manner that a high velocity of water may be obtained, and thusdecrease the size of the Water-passages. I attain this object by theconstructions shown in the accompanying drawings, in which- Figure 1 isa vertical longitudinal sectional view of a device embodying myinvention. Fig. 2 is a horizontal longitudinal sectional view taken atright angles to Fig. 1. Fig. 3 is a vertical transverse sectional viewof the same.

Like parts are represented by similar letters of reference in theseveral views.

In the said drawings, a represents an outer casing, preferablycylindrical in form. a is the inlet-opening, which leads thereto.

a b and bare the water-wheels, which are lo cated at each end of theouter casing or cylindrical penstock a and arranged to discharge intothe discharge or draft tubes 0 and c. The wheels 6 are placedeccentrically between the ends of the casing or penstock a, and adivision is formed in the penstock by means of the inclined plates orcones d d, the outer edges of which cones are bolted to thechute-frames, and the inner edges extend from the chute or gate openingsof the wheels at an angle until they meet at or near the center of thecasing at or come in contact with the inner periphery thereof. Theseplates cl and cl,if extended until they meet,would form substantiallycone-shaped deflectors; but in view of the fact that the wheels seteccentrically to the casing the perimeters of the cones are cut olf, sothat the length of the inclined side of each cone is increased as itextends around the cylinder. The outer casing or penstock is alsofurther provided with plates e and e, which plates are bolted to theouter casing at their outer ends and are bent in such a way that theinner ends of said plates meet at the chute or gate openings of thewheel and at one side of the inlet-opening a. These two plates, togetherwith the outer casing, form a spiral-shaped passage extending from theinlet-opening around the wheel.

-'The inclined. plates or cones (Z and (1, being set into the casingthusformed, also divide the space into two chambers, one for each wheel, andby reason of the decrease in the diameter of these cones, as beforedescribed, this space is reduced in both directions, so that the waterwhich enters the cylinder is deflected around the wheels in a spiraldirection and also in a lateral direction, thus decreasing thewater-space from the point of inlet to the point at which the last ofthe water is finally utilized. This not only gives to the wheel a supplyproportionate to the use, but also gives a velocity to the water whichpermits the use of smaller passages than wheresuch velocity is notobtained.

Within the space formed by the cones or division-plates d and d I placea gate-rigging, and also by the constructions to be described form asupport for the main or wheel shaft. Each wheel has its own casing,which will be formed in any suitable manner, preferably.

with the crown-plate b the chutes'b and the cylinder-gate 19 Thecylinder-gate b is adapted to be moved through a suitable circular slotin the crown-plate b and pass down along or in front of thechute b Foroperating this cylinder-gate I employ, preferably, for each gate tworacks b and b". These racks are T-shaped-that is, the main stemconstitutes the rack and the cross-bar of the T constitutes a foot orprojection which extends out and is bolted onto the edge of thecylinder-gate. Each of these racks is operated by a pinion b on a shaft12 which extends through the outer casing a at a point where the cones(l and d are cut off so as to leave a suitable space, as shown in Fig.2. The gate-operating racks on each wheel are placed in oppositedirections, and each of the shafts b is also provided with plain rollsor wheels I)", placed opposite the pinions on the othershaft,tlieserolls or wheels beingadapted to come on the back of the racks and holdthem in contact with their operating-pinions.

To the crown-plates of the wheel-casing for the wheels 1) and b there issecured the yokes 19 which yokes are also bolted or otherwise secured tothe chutes of said casing. These yokes on their inner sides arepreferably connected by circular plates or rings 1) and Z7 which arebolted together, as shown in Fig. 1, thus firmly connecting thewheel-casings and forming a solid connection through from one end of thepenstock to the other. To these yokes or to the frame thus formed I alsopreferably secure a bearing 7 for the main wheel-shaft I), which may beextended through the penstock and the draft-tubes c and 0' throughsuitable hearings in a wellknown manner.

In forming the deflecting plates or cones d and d and the partitionswhich divide the penstock into the scroll-shaped chambers I do not soconstruct the plates that they will be a complete bar to the water, butsimply use them as deflectors, the parts being so connected that thewater may find its way through into the central chamber, in which thegaterigging is located, and thus furnish a backing for the plates whichfor this reason may not be of great strength. The gate rods or shafts,however,will be passed through suitable stulfing-boxes in the usual wayto prevent the escape of water. The yokes or framework connecting thesame are also provided with suitable bearings Z9 for the gate rods orshafts b so that the entire gate-rigging, as well as the main shaft, issupported within the chamber formed by the deflecting-plates.

I have shown the spirally-arranged casing with the inclined orcone-shaped deflectingplates in connection with the cylinder-gate; butit is obvious that this may be used with any other formof gate withequally good results.

Having thus described my invention, 1 claim-- 1. In combination with theouter casing or penstock and a wheel supported at each end thereof, theinside cones extending to theinner periphery of said casing formingdeflectors for the respective wheels, the said wheelcasings being joinedtogether by a framework which lies wholly within the space inclosed bythe cones, substantially as specified.

2. The combination with the outer casing having the inclined plates orcones extending from the perimeters of the respective wheels at an angletoward each other and the inner periphery of the'casing so as to deflectthe water to the respective wheels and form an inner chamber, the yokesextending from the respective wheel-casings and joined together whollywithin said chamber forming a solid connection from one end of saidpenstock to the other, and gate-operating mechanism on said yokes andinclosed within said chamber, substantially as specified.

3. The combination with the outer casing or penstock and the respectivewheels located at each end thereof eccentric to said casing, and saidcasing being formed cylindricalshaped as described, inclined cones thecones being cut off at the perimeter by cylindricalshaped casing so asto form chambers reduced laterally, su bstantially as and for thepurpose specified.

4E. The combination with the outer casing or penstock, the wheelslocated at each end thereof, the angularly -arranged plates or coneswithin said casing forming deflectors for said wheels and an innerchamber between said wheels, and the framework connecting the casingsfor said wheels which extends through said chamber and is connectedtogether wholly therein, gate-operating mechanism in said chamberconsisting of T-shaped racks, pinions operating the same, and looserolls or wheels operating in connection with said racks, substantiallyas and for the purpose specified.

5. The combination with the casing or penstock and the wheels therein,and the angu larly-arranged plates or cones within the easing, theplates or cones being placed eccentrically within the casing tocorrespond to the wheels which are similarly placed, an inner chamberbetween said plates and cones, gaterigging wholly within the chamber andgateoperating rods extending through the penstock or casing at a pointbetween the plates or cones where the same are cut off at the perimeterwhereby the said gate-rods are out of the way of the flow of the water,substantially as specified.

6. The combination with the outer casing having the inclined plates orcones extending from the perimeters of the respective wheels at an angletoward each other and the inner periphery of the casing so as to deflectthe water to the respective wheels and form an inner chamber, yokes orsupports extending from the respective wheel-casings and joined togetherwholly within said chamber forming a solid connection and adapted toreceive the cylinder-gate when moved through the crownplate, andgate-operating mechanism on said supports and inclosed within saidchamber, substantially as specified.

In testimony whereof I have hereunto set my hand this 13th day ofOctober, A. D. 1898.
